That was the finding of the Sacramento County Coroner's office released on Friday. A press release from the county also classifies the manner of death "homicide."
No further information was provided concerning the cause of death of 5-year-old Tatiana Alexia Rose Garcia.
Her mother, Aquelin Crystal Talamantes, of Davis woman is accused of murder after her 5-year-old daughter was found unresponsive in her car trunk on Sept. 26.
Along with the murder charge, Yolo County prosecutors have alleged that Talamantes, 29, beat her daughter, filing a second allegation of assault on a young child with force likely to result in death.
Sacramento and Davis police arrested Talamantes about 2:35 p.m. Sept. 26 at a relative's apartment on Pocket Road in Sacramento after authorities said Talamantes drove there from her home in Davis with her 4-year-old son - and with her unresponsive daughter in the trunk of her car.
Talamantes' relatives grew concerned and called police when she arrived at the apartment with the boy but without her daughter, authorities said. Mother and daughter had been seen together in Davis earlier in the day, relatives told police.
Soon after Sacramento police arrived at the apartment, they discovered Tatiana in the trunk of her mother's car. With the help of neighbors, they tried to revive her.
She later died at a local hospital. It remains unknown when the girl was placed in the trunk.
